Abstract:
Electronic-grade ultrapure water(UPW) is the basic production material for semiconductor manufacturing. It is in great demand and requires extremely high water quality〔resistivity>18.2 MΩ·cm,TOC<5 μg/L(carbon)〕. With the requirements of the independent development of China’s electronics industry,the demand for electronic-grade UPW will continue to increase,and the water quality requirements will become increasingly strict. However,the preparation of electronic-grade UPW in China faces three key problems. Firstly,the key materials,equipment and technical processes required for the preparation of electronic-grade UPW are monopolized by foreign manufacturers. Secondly,the water quality standard systems and analysis methods of electronic-grade UPW are completely backward. Thirdly,the diversification of supply water sources significantly increases the difficulty of production for electronic-grade UPW. To this end,it proposed to speed up the research,testing and application of domestic core material equipment and key technology processes,establish an advanced standard system for water quality indicators and leading detection methods and platforms,and develop new ultra-high standard technical equipment and processes to achieve three solution methods for diversified water production. It is hoped to support the independent preparation of electronic-grade UPW in China.

摘要:
电子级超纯水(Ultrapure water,UPW)是电子行业的基础性生产资料,需求量大且对水质要求极高〔电阻率>18.2 MΩ·cm,TOC<5 μg/L(以C计)〕。随着中国电子行业自主化发展的要求,电子级超纯水需求量将持续增加,水质要求也将日趋严格。然而,中国在电子级超纯水制备领域面临3大关键难题:(1)关键材料设备与技术工艺被国外厂商垄断;(2)水质标准体系与检测能力全面落后;(3)电子级超纯水的多样化供水水源导致反渗透产水中电中性小分子有机物浓度升高且组分更复杂,加剧了电子级超纯水的制备难度。为此,提出应加快国产核心材料设备与关键技术工艺的研发、试验与应用工作,建立水质指标先进标准体系及领先检测方法和平台,开发新型超高标准技术设备与工艺,以实现多样化水源生产的3条解决思路,支撑中国电子级超纯水自主化制备。
